Overview of Ortho Evra (The Patch)
The Ortho Evra Patch is a combined estrogen/progestin adhesive patch worn on the skin. A new patch is placed in one of four locations-buttocks, abdomen, upper torso or upper outer arm once a week for three weeks in a row, followed by a 7-day patch free week. The patch requires a visit with a healthcare provider to get a prescription, and a visit to the pharmacy to get them.
How It Works
The combination of hormones works by keeping the ovaries from releasing an egg (ovulation) and less often by thickening the cervical mucus, which prevents the sperm from entering the uterus.
